Good music becomes great when you hear it through Polk's db Series car speakers. Polk engineers use laser imaging to determine the ideal combination of speaker materials and design to eliminate distortion. The resulting technology produces speakers with smooth frequency response, sharp detail, and the ability to play music at high volumes without strain.

Polk's versatile db6501 component speaker system features 6-1/2" woofers made from a polymer/mica composite and durable rubber surrounds that won't fall apart under stress from heat, moisture, or time. Liquid-cooled 1" silk/polymer dome tweeters use powerful Neodymium magnets to deliver precise high-frequency reproduction, enveloping you in bright musical detail. You can surface- or flush-mount the tweeters with the included swivel-mount cups. Just aim the tweeters so they broadcast toward your ears, creating a powerful stereo image.

External crossovers direct the right frequencies to the tweeters and woofers to maximize their performance, and their housings let you hide all wiring for a clean, professional look. These speakers feature stainless steel mounting hardware and muscular ABS grilles that will add a stylish touch to your car's interior. And Polk certifies their db Series speakers for marine applications, so they're a great choice for your boat, motorcycle, or ATV.

Priced per system

Product Highlights:

component speaker system includes two 6-1/2" woofers, 2 tweeters, and 2 crossovers

Why install component speakers?

A component speaker system gives you the best possible performance from your car audio system. A system consists of separate woofers, tweeters, and crossovers, each designed to cover one specific range of frequencies. As separate components, the woofer can move freely to deliver more powerful performance, while the tweeter can be custom-mounted in a better spot up closer to your ears, revealing a whole new world of detail. Separate crossovers are far superior to the simple filters wired into full-range speakers, so the components work together for smoother, more focused sound.

New business plan

I own a 2014 Jeep Wrangler. I found a dealer to install these, even though he doesn't carry the Polk Audio brand. He asked a couple times why I don't want the Rockford Fosgate/Kicker, or other brand speaker (which he sold). He also wanted to sell me a subwoofer. I told him these have better specs. He was unimpressed. I have Polk Audio front and rear matched up with the new high power Sony receiver. When the installation was done, he turned up the volume for a test run. At 100% volume, he began to smile and his eyes got wide. He said "Man, is this clear. It sounds great!" I told him he should start selling Polk Audio and he responded "I probably should." We both agree, I do not need a subwoofer. I can't imagine why people would spend more money to buy lesser speakers? Look at the specifications people. These are amazing speakers with top notch materials and they are marine approved. Good thing with the top off of the Jeep. I had Polk Audio in my last Jeep and will continue to buy Polk Audio as long as they make the best speakers on the market.

Pros:Best frequency response I could find in a 6.5 inch round. Top of the line materials. Excellent power handling. Marine rated, which is great for having the top down. Excellent sound (clarity and quality). Not that I care, but they look great as well.

Polk Audio db6501

Speakers are fine. Installed 4 of them - front and back. Installation kit is great - good options for installing the tweeters. Sound is OK for what they are. Not driving with them with a separate amp, so that my limit what I can get. Highs and lows are not stand-out, but reasonably happy with them.

Awesome performance for the price

Installed Polk DB-6501 components last Oct., 2014 after taking delivery of our 2015 Honda Fit. Coming from the wife's Lexus RX350 equipped with the factory M. Levinson system, I knew my sound requirements would be unhappy with the stock Honda sounds like that of my previous '08 Fit. Wanting to maintain the OEM HU (reverse park camera integrated to HU screen), upgraded the audio components with an Audison processor, a Kenwood 4 channel Excelon amp and a Kenwood powered sub. To get the maximum results, installed sound-deadened (using MLV, CCL, CLD tiles) since the whole interior was taken apart to do wiring simultaneously. It took me two weeks working a couple hours daily. In the end, worth all the effort. With the OEM HU retained, the steering controls including phone controls are maintained. Sound difference however, is astounding!!! Every instrument can be clearly heard as well as distinct separation from L-R + F-R. My only advise would be to use a decent amp to power the Polks to achieve its potential. Using the power from any factory OEM HU would be giving these speakers an injustice. If wanting to upgrade the cheapo factory speakers, your better off to buy more efficiently rated speakers (cheaper-10 to 30 watts). Supplied speaker brackets need a bit of minor modification doable with a Dremel to make them fit the Honda's factory holes. No sheet metal drilling was required. Driving this little eco sub-compact is now extremely pleasureable both city & hwy.

Pros:- easy install
- defined highs, mids

Cons:- needs a decent power amp
- tweeter is pretty sharp but can be toned down through the crossover

Very Efficient But Sound A Bit Hollow In My Application

Written By sirbOOmdotcom, United States on Monday, January 26, 2015

These are clearly MUCH more efficient than my stock speakers. I bought these due to a combination of price and efficiency. I have the doors deadened and sealed and both the tweeter and woofer are in the door as close to the stock speaker grills as possible. I guess I'm used to the high-end speakers in my other vehicle or maybe it is the, let's be honest, cheap PPI ION amplifier (hey... it's a commuter car, I don't want to dump money into it). They are louder than stock on the same power but they sound almost the same as stock - there really isn't much (if any) improved detail or air. The midbass is tighter and a teeny but more plentiful, but vocals sound a bit unnatural - the word "plastic" comes to mind when I think of how vocals sound. Alas, there are nice things about these. They're shallow and fit in 2006 Kia Spectra doors (after gutting the stock speakers) like a champ. The tweeter was a pain to put in the stock location but I got it in there because I'm the man (and I think the stock location for the tweeter is partially to blame for what I'm missing in this speaker set). I wasn't provided mounting screws, which was annoying, but everyone has some screws at home so no big deal. Overall, was it worth it to install these? Well, sure... the stereo is louder and tighter overall better... just not hugely so.

Great Sound

Written By IsraelE, Texas on Saturday, December 13, 2014

Speakers sound great in my Mazda 6. Speakers do not fit in the front door with the brackets that were provided by Crutchfield. Luckily the installer was able to repurpose stock speakers to install these. Speakers were installed with an amp, there is more than enough power.

Giant Improvement

My son and myself installed these speakers in the front doors of his VW Passat and, wow, huge difference in sound, the car has a factory sunomi head unit which sounded ok, we had planned to get newer head unit later but after hearing these system with these speakers I think we will just wire a control wire to the cd chager input and get another pair of these speakers for the rear doors and a powered sub in the trunk for his hip hop and rap

Great Sound

Sound quality is great. I had some issues with one of the tweeters but Crutchfield sent me a replacement and now all is well. I think the crossovers sent are a bit large if you have limited space but work well.

Pros:Sound quality is great!

Cons:tweeters are difficult to install if you don't have a place for them but the hardware makes up for it. One of the tweeters had a rattle and seemed blown right out of the box but it was quickly resolved by Crutchfield! (Great customer service!)

Great sound

These speaker sound great no amp installed yet. They sound awesome, removed the bose speakers from my GMC Sierra and placed tweeters on the original site on the pillars. I have Alpine 6 1/2 type S in the rear. It took some modification to place there as I had to cut the inside of the bose tweeter cover for the back to be flush but it was well worth the effort for better acoustics. A new head unit is the works (I'm thinking the Kenwood DDX471 HD) and will be pushing them with a 4 channel Alpine I currently own.

Polk Audio DB6501

Replaced stock speakers in my 2007 Saturn Aura and WOW!!!! what a huge difference. These speakers sound awesome with my Pioneer HU. My highs are so much clearer and the mid bass is just right and my amp isn't even hooked up yet! I highly recommend these if your looking for a high quality component set of speakers!

Blown 2 in 18 months

Written By Anonymous, San Francisco, CA on Saturday, August 09, 2014

I just blew my passenger side speaker, and I was bummed, because of the price I paid for these. Then, as I was looking up the warranty info, I remembered that I'd actually blown one of these Polks right after I bought it. I have an amp, bridged to 90w RMS per channel, with the gain set to about nill, and an Alipine HU I purchased here. After reading several reviews here about build quality on the Polks, I realize it's not me; it's them.

Great Product....Excellent Quality

I found the Polk speakers to be of excellent quality. The speakers were competitively priced. I was unaware of what I was missing from the tweeters until these were installed. The bass is also a noticeable improvement. The 2-way speakers were very easy to install. The component set took a little homework for a novice(my first install). The supplied speaker mounts and wiring harnesses were priceless. However, the Crutchfield team is truly awesome with their support. They were there to help even on the 4th of July.

Great Speakers in 2007 Silverado

I bought these speakers for my 2007 NNBS Silverado because I heard the DXI series at a BB. Read the review online and many people rave but say you need to amp them. I have not amped them and let me say that they sound fantastic. Much better detail, accuracy and clarity over the stock Silverado speakers. I did put in Dynamat around the opening and sealed much of the door. But these speakers are so pleasant to listen too. Not over bearing with the tweeter, just a smooth sound. Woofer puts out some great mid bass. Some people feel it lacks, maybe for hip hop..but I think it puts a nice bottom end to most music. If you are on the fence about these speakers, just go with your gut and buy them. You won't regret them at all.

Pros:Great speakers! Cannot imagine getting better sound

Cons:Crossover was a bit tricky to install due to size but I made it work.

What a difference!

I really like these speakers! I didn't find them too bright for the music I listen to (rock, blues, country and some classical). The bass is slightly lacking, but not overly so, in my opinion. I have a Kenwood Excelon head unit with lots of adjust ability but no external amp or subs (for now). The difference between these and stock paper cone speakers is probably why some people thought they are 'too bright'. You will hear so much more of the music that it was lacking before, and it might just come down to tailoring the sound with your preset, or manual equalization of your head unit. If you run these with a stock head unit and don't have much adjustability, by all means step up to an aftermarket unit. I run these in the front of my 99 Tacoma extended cab with the Polk coax 651's in the rear. I love the sound of Allison Krauss through these. I really agonized over the placement of the tweeters, but ended up putting them in the sail panels and really enjoy the sound. If you like more bass heavy music, add a sub, you would with any speaker, Overall, for my listening tastes these were a great choice!

Pros:Huge improvement over stock speakers, exactly what I was looking for.

Awesome

Written By MK4 Rollin, Minneapolis, MN on Monday, April 21, 2014

Great sounding speakers at a really reasonable price. Definitely will not disappoint so you can't make a bad decision with these. Does a great job at separating sound which factory speakers do an aweful job at. Overall great system.

Polk Audio db6501

I love these 6.5's. Once you supply them the power they want, the are beast! The tweeters on the other hand are killing me! It doesn't matter what volume level, or what gain setting on the amp I use. They are shrill/very bright. It's driving me crazy trying to get these tweets to sound right with the rest of the system. I have the -3 db set on its crossover and that helped but not near enough. Turning the gain on the amp down helps but then you lose the power the 6.5s crave. I'm at loss with these tweets.

Pros:The 6.5's are amazing for this price point when supplied the power they want.

Cons:For my ears...These tweeters suck!! I may just have to replace them.

Great Speakers for under $200

I have these in my Subie off of an Alpine 4ch. I just put the same two components in my son's car but bridged the amp so each component is getting 150w instead of 50w. What a difference! I have now ordered a separate amp for my sub so i can bridge my amp for the components.

Pros:Cost, Sound

Cons:Play with the settings on your amp to get the best lows out of the mid

What a difference!!

What a difference from factory '07 Ridgeline speakers... arrived on time and installed the woofers in less than an hour, thanks to good directions, wasn't all that impressed at first (I still hadn't installed the tweeters) and after getting a few extra little things to install the tweeters I did a custom door integration rather than fiddle with the dash and door connectors and after powering up and a few minutes of "tuning" with the stock head they sound AMAZING! Mid range in crystal clear and tweeters sing the highs like nothing else! I don't want to get out of the car now!! Looking to order second pair for rear doors and custom mount those tweeters too, they are a little quieter than factory speakers (as expected) but can easily handle a large amp install, bottom line I love these things!

Pros:Absolutely amazing Mid range and Highs, Tweeters have a "modern" look that fits in well, as well as flush or surface mount options

Great Speakers

I paired this 6 speaker system with the Sony MEX-8T3100P CD receiver. (Please see my review for that product for more details.) These speakers work well with the receiver. There is a separate pair of tweeters! The bass is thumpring (if you like that sorta thing.) The balance is great. No bad words for the speakers. I installed the speakers in my 1998 Dodge Durango. An almost 1000% improvement over my old partially working speakers (1 front, 1 back.)

Pros:The speakers sound amazing. I get all 3 levels clearly. The tweeters provide a clear sound and they are mounted on my door. There were no separate tweeters with the factory setup. My installer cut a hole in the door especially more the tweeters. Very glad I made the change. These value speakers work especially well with my receiver. Even with the installation fee, they are still worth the value.

Huge Sound boost

I used these to replace the factory speakers in my door. Although replacing the existing 1" tweeter was a bit of a project, the main speakers fit like a charm. These were the last of a full Polk Audio upgrade in my vehicle and I am enjoying listening to the full range in my music. This is an outstanding upgrade.

2010 Sonata Upgrade

Replaced the front door speakers with the 6501's. Fantastic improvement in clarity and quality. Set the xovers to -3db and with the 651's in the rear doors my car sounds great for the ride to work and back.

Polk db series

Installed these 6501's along with a pair of 691's in my 2006 Camry 5+ years ago; mated to an Alpine MRP-F600 amp. Mounted the tweeters in front of the door latch; the imaging is incredible. I love my music LOUD, and these speakers have easily handled everything I've thrown at them. Very impressive!!!

Awesome

These speakers sound incredible. Couldn't be more happy with these Polks. They sound crisp and clear full range at all decibel levels. I installed them in a 2002 Subaru Forester, they have a manufactured place for the tweeters in the front door moldings. I was questioned the fit of the tweeters until I got the door back together and wal-ah.....perfect fit. I would recommend these speakers to anybody! I would also agree with the previous reviewers, these speakers need more power than a standard deck output and spend the money on some kind of sound dampening material for the doors. I bought a product from Meijers called Scoche (half the cost of dynomat and its the same thing). I matched mine with a 45 watt RMS amp:

Amazing

Written By jb, Zachary, Louisiana on Tuesday, July 02, 2013

Just finished installing 2 pair in my crew cab 2012 GMC Sierra. I kept the factory head unit and added a Pioneer GM-D8604, 100w rms x 4, to power them. All I can saw is WOW! I am beyond satisfied and would not hesitate to recommend them. Do yourself a favor and amp them up. They are rated to handle the power for a reason. I am also very happy with the bass. I will be adding a sub later, but for now I am completely satisfied!

Pros:They rock! They scream for more power and easily take what you give them.

Nothing but trouble

Purchased these a few years back, they were working fine for about a few months then they decided to develop a crackling/distorted sound from the woofers. Called Crutchfield, gave them the specs of the amp used, headunit etc, nothing out of the ordinary and they sent out a new set. Swapped them out and they were good for the rest of the year. Last year they exhibited the same crackling at soft/loud volume levels. Too late for an exchange from Crutchfield. I'm so put off with the entire purchase, I could not with all honesty recommend these at all. They are currently being powered with a JL Audio XD 700/5. What's ironic is the pair of DB coaxials I have in the rear of my car are working just fine. Something about the DB components fails far too soon. First and last set of Polks for me. If I could give these no stars I would.

Pros:Higher wattage, seemed to be built well enough to give years of trouble free service.

Cons:Crackling sounds, failed crossovers/voicecoil. Poor runtime and fail just after the warranty expires.

Stoked!

These speakers ROCK!!! I initially made the mistake of trying to re-use the factory JBL AMP in my 2006 Tundra. What a major let down. Fortunately, the great staff at Crutchfield corrected the problem and advised a 800w 4 channel amp from MTX. This made all the difference in the world. I am now TOTALLY STOKED!!

Great speakers

Written By Chris H., Raleigh, NC on Saturday, June 08, 2013

I have a set of these in the front and polk 6x9's in the rear of my 00' civic and they sound great! I have a jvc HU and a pioneer (champion series/ class D) 4 channel amp powering these and they are loud and clear. I have no sub and get great bass response all around.

Not Bad

Written By Matt L, Coeur d' Alene, ID on Monday, March 11, 2013

Not too bad, they severely lack in bass though. I do have a sub for that, but it's kinda irritating. The tweeter are way too sharp in my opinion and need to be turned down at the crossover. They do sound clean and great on an amp.

Pretty Good

This is my second set I purchased but I haven't installed yet. This set (4 total) are heading into a 2000 TA. The first set I used to replace all 4 door speakers in an 08 Avalanche. I have them hooked up to an old school Lanzar 240s amp with the gain at about 75%. They are crisp and clear until you have the music way up - up at unsustainable listening levels. They handle the power and I had to turn the gain on the crossovers down for the tweeters because they are producing ear piercing highs. Bass is OK, could be better but for what they are - they are good enough. The sub takes care of the boom. No problems with speakers - been in the truck over a year and they get abused every day with the music up during my commute. Don't know how they will hold up as competition speakers but I guess I will find out once they get installed in the TA

Nice until the tweeters died

I installed these speakers in my show/race car 3 years ago, and they don't get used everyday. The engine is loud, so I did not notice that the tweeters were not working until a few months ago when I had the radio on while I was working on the car. Then I realized that both left and right tweeters were dead. I had some old component tweeters and I hooked them up for the time being. But I was disappointed that they did not last long.

Polk DB6501

Written By ken, Amarillo,Tx on Saturday, January 05, 2013

These have got to be some of the baddest speakers on the planet.sound is running through Kenwood KDC-X759 Excelon powered with Rockford Fosgate 350S; 87.5 RMS x 2. Sounds like a outdoor concert.Amazing!!!!!!

Good while they last

I have mixed feelings on these speakers. I have gone through 3 sets. I purchased them a couple of years back to install in my 06 Chrysler 300C. I am powering them with a D450.4 amp. I have 12" subs on 2 of the channels so really wasn't looking for these to produce a lot of bass. I ran them with the gain on the amp almost completely down. One of the woofers quit working and Crutchfield was outstanding. They sent me a replacement set so I could change the whole system or just the speaker that blew. A few months later another speaker blew again and once again Crutchfield was great. I thought they were blowing due to fault of my own. I run my system HARD. This time I adjusted the high pass filter on my amp and headunit to pretty much take out all of the bass going to the components. That worked good for a year and then out of no where, both of my tweeters quit working. What the world???? This happened just outside of my 1 year warranty so I am out of luck. I am going to replace them with 3.5 speakers. As much as I am trying to find fault in myself for running my system so hard, I am having a hard time doing that.

Pros:Good sound, easy installation. Great customer support from Crutchfield.

Cons:Reliability. Every component of the system has broke at one time or another with the exception of the crossovers.

Amazing when used what they are intended for!

Written By Nate, Salem, Or on Monday, September 10, 2012

There are a few things people need to realize. I have read reviews where people are not happy because there is little bass out put. These speakers are meant to be used for more of a mid-bass and highs, sound to ACCOMPANY a sub or subs. You wont get power bass out of these since they are not designed to do so. Other people say they sound terrible when run off of their head unit. They NEED to have an amp. Also, it is possible to damage speakers by UNDER powering them, as well as over powering. That all being said, I have two sets of these in my 93 4Runner in all four doors, powerd by an Alpine PDX 4.100 amp. I have run them for over 5 years now and they still sound amazing. Great mid-bass and clear crisp highs. I am also running one Kicker Comp VR 10" sub in a slotted box, powered by an Alpine PDX 1.600. This combination works wonderful for all music types,and is not overkill in any way. It was very reasonably priced for the quality. Sorry if this is a rant or too long, but people need to know things like this before spending money, then being upset or disappointed. These speakers are wonderful. I have been in the car audio business for over 18 years now, and these impressed me.

Polk Audio db6501

Replaced some Pioneer component speakers with these in the front doors of a '09 Accord. The Polk speakers cost $90 more, but you really get what you pay for. I'd recommend forking out the extra money if you really value sound quality. These speakers bring out every little nuance/detail from your music. I would not buy these speakers without buying an amp that provides adequate power. They need proper power to do them justice. I am running them through a Sound Ordnance M4100 amp and they sound amazing. Also would recommend installing Dynamat in the front door panels...it creates a great bass response. Before the Dynamat I had no bass.

Great Sound

The speakers are / were an excellent addition to my stereo, I loved them. However, they didnt last very long, almost 2 years, then the speakers became soundless. First the left side went, then the right side. The speakers were more powerful than my stereo, so I know I didn't blow them out. Time to look for another mfgr for my next set of speakers.

Installed Twice

OK, the first set was in my GF's 4Runner. It sounded so good I immediately ordered a set for my Wrangler JK. Actually made a more noticeable, remarkable difference in the Toyota, but that is likely due to the crappier existing speaks. Vocals, guitar, and hand claps in live recordings that I've never heard before!

Fantastic Speaker when powered correctly

Written By RaulH, Clawson, Mi on Monday, July 09, 2012

I have these speakers coupled with an Alpine MRX-F30 amplifier and holy cow can they hit! Extremely clear vocals, bass is very tight and punchy, just what I expected. Now, I truly understand what good bass from a component speaker can sound like. Anyone saying these cannot produce bass does not have enough power to them. They Love power.

Pros:Outstanding speaker for the price, sound as good as speakers costing three times as much!

Not too bad...

Not a bad set of components. The bass is completely missing, but the accuracy of mids and highs is much better than the stockers these speakers replace. I am hearing things that I've never heard before in my music. I strayed from my usual Infinity purchases to try these Polks, and while they aren't fantastic enough to do it again, I am not too disappointed.

Pros:SQ accuracy, adjustable crossovers (although I use 0db; -3db cuts too much out and +3db is too harsh)

Quality issues apparent

Purchased my first pair from Crutchfield and installed them in a 07 Subaru Impreza. They sounded great for a week then started to distort at any/all volume levels. Crutchfield was great in shipping a replacement set out to me, which did the trick. Unfortunately that only lasted for about a year and now they are exhibiting the same distortion and any/all volume levels. Two times is enough for me to look elsewhere. The quality isn't there. Tweeter screens come loose and fall off in extreme heat during the summer.

Good Speakers

Cons:Not the problem with the speaker but I had to fabricate a bracket to be able to install the speakers. The bracket that Crutchfield supplied did not work. I gutted my factory speakers and mounted the bracket that Crutchfield sent to the factory bracket. In the end all worked great.

Great factory upgrade, ideal for most.

Written By Kaltenberg91, Wisconsin on Friday, May 25, 2012

Have owned these for a couple years and use them every day. They are a great upgrade from factory and give a rich clear sound. When used with a subwoofer at low to moderate volume they have a really balanced sound. After some time and occasions where I cranked them higher than normal listening volume they've began to show some wear. Still sounding great at normal volumes they begin to distort more rapidly than before as higher volumes are reached. Overall great speakers, and definitely cant complain with the price. Don't buy your gear anywhere besides Crutchfield, they give you everything needed to make installation quick n easy.

Pros:Very clear, crisp sounding speakers.
Best you can buy for the cost.

Cons:Lacking bass (as far as 6.5" components can go)
High volumes had shown "wear" on the speakers.

Polk Audio ..... only If you put them in the right spot

So I got these and was a little surprised by the wait. They were very light but like mentioned in the other review do not let that fool you they are LOUD. However they are a little on the Scratchy side. I have these in the front and back powered with a Hifonics 4x100 rms channel amp. In the back they sound very crisp and clear and don't have the ear irritating Scratch. Though in the front they do have an annoying high pitch scratchy sound when vocals or really anything is played at high volume. I figured that the reason this was because the tweeter was closer to my ear then on the back. So If you get these make sure u put the tweeter pretty close to the mid.

Pros:pretty solid for the price and really loud.

Cons:could have more bass but whatever I have subs so it takes care of that. Much rather have gotten the DLS Ultimate UP6i but because of the buy one get one half of i went with these.

Polk Audio db6501's sound amazing !

These speakers were just what my Tahoe needed. They went in the front doors very well. And with one good hole saw they went in the back doors as well. A huge increase in sound quality and imaging. They are run from an Alpine head unit with the Power-Pack added, a must for the price. I highly recommend them, they can handle power as well.

Polk Audio db6501

I bought these to replace my front factory speakers in my 02 Z71,and let me tell you they sound great and all i"m running for power is a new kenwood cd player thats 50 watts,I cant wait to hear them with a amp.they were kinda hard to put in the crossovers i had to mount under the dash,and the factory tweeters were alot bigger than the polks so I tore the old tweeters apart and used the old mounts to mount the new ones on..took me and 2 other guys 2hrs but well worth the time..great speakers with a great sound make sure you have a amp to push them to get the best sound out of them..I would recomend these to anyone that want a great sounding speaker without breaking the bank..

Written By James, Los Angeles on Sunday, September 04, 2011

They sound way too harsh. The tweets are annoyingly piercing. The mids aren't clear and almost non-existent. My factory speakers sounded better than these. I'm powering them with a polk audio pa.1100.5 amp.

I have the Polk mm6501s in the front and they sound 10x better. They're much warmer, have decent bass coming out of the woofer, and the tweets sound very detailed.

Good for everything except rock

I purchased two sets and I have used them in several configurations. As others have said, they really need some amp power in order to sound good. They also require some experimentation in order to get the best sound. My findings were:

- The mid-bass is great if you don't choke it off by sealing them off in a set of speaker baffles, especially the "low profile" ones. (These are marine certified, so you don't have to worry about protecting them from water.)

- As another reviewer mentioned, they don't do well reproducing rock electric guitar tone. Definitely better for jazz, classical, and even hip-hop and techno.

- The highs can be a little bright, but they are definitely not as harsh as the hard dome tweeters from Infinity. Be prepared to experiment with tweeter placement, aiming, and treble equalization in order to get it just right. (I found that I actually liked them better mounted low, near the woofer, than I did on the sail panels.)

Also, I should mention that I put one set of these in a boat, and they are heading into their third summer. Driven only by the head unit, they play loud enough to hear over the (inboard) engine, but they do get distorted at high volumes.

Other than the weakness in rock guitar, my only complaint is that the install hardware quality could be better. Probably not an issue for most people, but things do tend to get bent/broken/worn over the course of multiple cycles of installing/uninstalling/moving the components.
